Marina is trying to make a model that shows Terrance that even though the water was no longer in the pot, it was not destroyed. She wants to show the principle of Conservation of Mass. Which model should she use to help Terrance understand that matter isn't destroyed when it changes?

• Water evaporating from a puddle

• Weighing a cup of water, freezing it and weighing it again

• Mixing oil and water

• Burning a log into ash

Said poured 5 cups of water into a bowl two weeks ago and placed it in the freezer. He took the bowl out of the freezer yesterday and accidentally left it on the counter while he was at school. When he returned home from school, the ice had melted in the bowl. Said measured the amount of water that came from the melted ice. Which should be the amount of water that is in the bowl?

• 6 cups

• 5 cups

• 4 cups

• 7 cups

John wants to create a model that explains the rain shadow effect. He wants to make sure he has the steps in the correct order. Label the events below from 1 to 4. What is the FIRST STEP in the rain formation process?

• Clouds fall lower in the atmosphere on the other side of the mountain and carry small liquid water droplets over land.

• Water warms and evaporates into the air.

• Clouds are redirected higher in the atmosphere by mountains produce rain.

• As the water vapor rises in the air, it cools and condenses to form clouds.
